" EYEGLASSES. I

To all whom it may concern v I Be it known that I, HAROLD K. PARSONS, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification. 1

i invention relates to improvements in eyeglasses and has particular referenceto that type in which pivoted spring pressed guards are employed for retaining the ,mountingin position on the face of the;

wearer. i 7

The leading object of my invention isthe provision of improved means for detachably securing the actuating spring for the said guards H l V I; f I 11 Afurther object of my invention is the provision of a new, attractive and readil v constructed and assembled'mounting.

Other objects and advantages of -my improved construction should be readily apparent by reference to'the following description taken 1n connection "with the accompanying drawings'and it will be understood thatImay make anymodifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention;

The guard' arm 5 bears on one'end the guard 7 of any suitable construction and is preferably provided on the opposite end with a finger Formed on one side of the or finger 9 adapted to be bent downwardly piece 8 for ready operation of the guard lever. lever adjacent the pivot aperture is :1. lugand have the terminal portion 10 thereof extending outwardly to form a slight shoulder. Resting upon this, shoulder isthe inner end of the spring 11 which is formed with a hook 12 for engagingthe finger 9,the

shoulder supporting thespring holding the same'in place,

spring it ismerely necessary to disengage the finger andthen laterally shift the spring until it is'out of engagement with the shoulder 10, when. it may In Figs. IV and V, I have illustrated a slight modification of my construction 'in which the lever 5 spans the bridge 4 "and the finger 9 is the terminal of the portion of the material instead of being ,bent down from'one side thereof, said finger-being provided with the shoulder retainer 10 and the spring having the hook 12 for engaging the finger. lnFig. I, I have shown another-slight modification in which the pivot 13 is integrally secured to the lever andadapted to the outer end bearing against the strap 3 of the mounting. TOI'BIHOVG the pass freely downward through the bridge,

said pivot being provided with a slot '14 and shoulders 15 whereby the spring may be en gaged' in the slot and under tension willrest on the shoulders 15 which hold it under ordinary conditions against accidental disengagement. Y Y i h I In that form of my invention illustrated in Fig. VII, I have shown the lever arm 5 as" der side of the spring, I form on the. innerendof. the-spring'an aperture 16 which receives the bent or shoulder portion 10 of the finger, whileto further support-the spring I formon'the outer end the offset portion 17 adapted to be. bent to-lie under the coils of 25 the spring and having a notch 18 formed in the terminus thereof to fit around the strap 3 and lock the outer end of the spring against rotation, the strap being provided with a lug 1 9 fitting beneath the portion 17 j of the spring to support the same. The form of my invention shown in Fig. XI'requires no particular description inasmuch as this form illustrates the same construction as that shown in Figs. I, II and III, with the exception that the spring and lever have been placed: on the upper instead of the under side of the mounting.

I that form of the invention shown in 1 Figs, X11 and XIII in place of forming the finger 9 with a shoulder I so dispose the lug 1 9;on the strap S that it will fit intothe aperture 20 formed in the outer portion of the spring, the lug thus supporting the spring while the spring is provided on its inner end with the inwardly bent notched or apertured portion 1 7, the notch or aperture 18 thereof engaging the finger 9 and frictionally resisting jdownward movement of the spring to supplement the'action of the lug 19 in supporting the said spring.

From the foregoing description taken in connection with the accompanying drawings, the construction ofmy improved portion for engaging the inner endof, the

mountings should be readily apparent and it will be seen that I have provided a construction embodying as its essential feature a piv- .oted guard arm having a depending finger spring in such manner that the spring may be readily detached therefrom when des red for removal and replacement withoutthe posi-tion of the guard being disturbed, and in 1 which when the spring is in position the in- ,ner endo he pr g l-mov upon pivotal movement of the guard to wind the spring while uncoiling of the spring will tend to shift the guardinto gripping positiOiI i While in the majo r -ityof-forms of my in- I ,vention illustrated,-I have shown what is commonly termed aflat spring, it willbe understood that most of the forms ,jshOWnare adapted for use with either flatfhalf round 9} l"9 ,1: -P. .i-I. g, al g m are p ticularly adapted for use with. the flat springs, and it is for that -reason that I have illustrated my mounting as equipped with I flat springs.
